Along with the worldwide increase in continuous left ventricular assist device (LVAD) strategy adoption, more and more patients with demanding anatomical and clinical features are currently referred to heart failure (HF) departments for treatment. Thus surgeons have to deal, technically, with re-entry due to previous cardiac surgery procedures, porcelain aorta, peripheral vascular arterial disease, concomitant valvular or septal disease, biventricular failure. New surgical techniques and surgical tools have been developed to offer acceptable postoperative outcomes to all mechanical circulatory support recipients. Several less invasive and/or thoracotomic approaches for surgery combined with various LVAD inflow and outflow graft alternative anastomotic sites for system placement have been reported and described to solve complex clinical scenarios. Surgical techniques have been upgraded with further technical tips to preserve the native anatomy in case of re-entry for heart transplantation, myocardial recovery or device explant. The current continuous-flow miniaturized and intrapericardial devices provide versatility and technical advantages. However, the surgical planning requires a careful multidisciplinary evaluation which must be driven by a dedicated and well-trained Heart Failure team. Biventricular assist device (BVAD) implantation by adoption of the newer radial pumps might be a challenge. However, the results are encouraging thus remaining a valid option. This paper reviews and summarizes LVAD preoperative assessment and current surgical techniques for implantation.
随着全球范围内持续性左心室辅助装置(LVAD)策略采用率的上升,越来越多具有复杂解剖结构和临床特征的患者目前被转诊至心力衰竭(HF)科室进行治疗。因此,外科医生在技术上必须应对因既往心脏手术操作、瓷化主动脉、外周血管动脉疾病、合并瓣膜或间隔疾病、双心室衰竭导致的再次手术情况。已经开发了新的手术技术和手术工具,为所有机械循环支持受者提供可接受的术后结果。为解决复杂的临床情况,已有报道并描述了几种侵入性较小和/或开胸手术方法,以及用于系统放置的各种LVAD流入和流出移植物替代吻合部位。手术技术已通过进一步的技术技巧得到升级,以便在因心脏移植、心肌恢复或装置取出而再次手术时保留原生解剖结构。当前的连续流小型化和心包内装置具有多功能性和技术优势。然而,手术规划需要仔细的多学科评估,这必须由一个专业且训练有素的心力衰竭团队来主导。采用新型径向泵植入双心室辅助装置(BVAD)可能具有挑战性。然而,结果令人鼓舞,因此仍然是一个有效的选择。本文回顾并总结了LVAD术前评估及当前的植入手术技术。
